Coolant-Resistant Digital Outside Micrometers

Measure parts inside CNC machines and other places coated with coolant and cutting oil. The display and battery cover are tightly sealed, so spraying and dripping fluids won't seep in.

With an LCD display, these micrometers give instant measurements—no need to read scales. Swap between inch and metric or set the position to zero, all with the press of a button. You don't need to reset the zero point since they retain their position when turned off, also known as absolute (ABS) positioning.

Mitutoyo—The go-to for machinists and engineers. Every part is made within a Mitutoyo automated factory and tested in-house in Japan. The spindle glides as you turn the thimble with a weighty, silky-smooth feel.

Starrett—Precision machined and tested in the U.S. These Starrett micrometers come packaged in their iconic red case, so you'll be able to spot them on the busiest of bench tops.

With SPC Data Output—Send measurements to a computer or data processor to store, analyze, and manage data. You'll need a data cable or SPC wireless transmitter and receiver.

Calibration Certificate—Choose these micrometers when precision measurements are required for quality control or by regulation. The certificate is traceable to NIST, so you can be confident your measurements are correct and consistent.

Friction Thimble—Control how tightly the spindle closes on your part without the risk of damaging it. You can keep extending the spindle in small increments once it reaches your workpiece but not enough to overtighten. The thimble will start to resist turning to let you know you’ve applied the right amount of pressure.

Ratchet Thimble/Ratchet-Stop Thimble—Best for consistent, repeatable measurements. The spindle stops extending the moment it reaches your part, so it won’t overtighten. Hear and feel a satisfying click that confirms you’ve applied the right amount of pressure.

High-Precision Digital Outside Micrometers

The most precise digital micrometers on the market, with increments down to five millionths of an inch. They're also our most accurate—their tolerances are tight enough to machine shims and calibrate pin gauges. Each one comes with a signed certificate of inspection, so you can trust your measurements are correct every time.

With an LCD display, these micrometers give instant measurements—no need to read scales. Swap between inch and metric or set the position to zero, all with the press of a button.

Go/No-Go Outside Diameter Gauges with Calibration Certificate

Gauge Shown

with

Variance

Indicator

With a calibration certificate traceable to NIST that says they've passed a test for accuracy, you can trust these gauges to confirm if your object's outer diameter is within tolerance. They're also known as snap gauges because they snap onto rods, shafts, and other cylindrical objects. To maintain their accuracy over time, they have a hardened steel frame and spindle that withstands flexing and temperature changes.

Indicators—Attach variance indicators to measure the difference between your part’s actual diameter and the expected diameter. They also come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.

Coolant-Resistant Wide-Range Digital Outside Micrometers

Check different-sized parts as you machine them without swapping between tools. These micrometers come with multiple anvils that you switch out, so you don't need to lug around a case of micrometers. Whether you're milling or drilling, the display and battery cover are tightly sealed, so spraying and dripping coolant won't seep in.

With an LCD display, these micrometers give instant measurements—no need to read scales. Swap between inch and metric or set the position to zero, all with the press of a button. You don't need to reset the zero point since they retain their position when turned off, also known as absolute (ABS) positioning.

Coolant-Resistant Long-Reach Digital Outside Micrometers

Take thickness measurements of sheet metal and other long, flat parts right inside CNC machines. The display and battery cover are tightly sealed, so spraying and dripping coolant won't seep in. These micrometers have a deep throat to reach the center of workpieces, away from the edge where deformities might skew readings.

With an LCD display, these micrometers give instant measurements—no need to read scales. Swap between inch and metric or set the position to zero, all with the press of a button. You don't need to reset the zero point since they retain their position when turned off, also known as absolute (ABS) positioning.

Mitutoyo—The go-to for machinists and engineers. Every part is made within a Mitutoyo automated factory and tested in-house in Japan. The spindle glides as you turn the thimble with a weighty, silky-smooth feel.

With SPC Data Output—Send measurements to a computer or data processor to store, analyze, and manage data. You'll need a data cable or SPC wireless transmitter and receiver.

Calibration Certificate—Choose these micrometers when precision measurements are required for quality control or by regulation. The certificate is traceable to NIST, so you can be confident your measurements are correct and consistent.

Ratchet-Stop Thimble—Best for consistent, repeatable measurements. The spindle stops extending the moment it reaches your part, so it won’t overtighten. Hear and feel a satisfying click that confirms you’ve applied the right amount of pressure.

Friction Thimble—Control how tightly the spindle closes on your part without the risk of damaging it. You can keep extending the spindle in small increments once it reaches your workpiece but not enough to overtighten. The thimble will start to resist turning to let you know you’ve applied the right amount of pressure.

Outside Micrometers for Small Holes, Grooves, and Keyways


	With Analog Display

Thin as a pencil point, the anvil and spindle slip into narrow spaces where standard ones won't fit. They're often used to measure the outer dimensions of grooves in pins, O-rings, and other small parts.

To find your exact measurements, read the scales on the sleeve and thimble. You don't have to replace any batteries, so these micrometers are always ready for the job.

Mitutoyo—The go-to for machinists and engineers. Every part is made within a Mitutoyo automated factory and tested in-house in Japan. The spindle glides as you turn the thimble with a weighty, silky-smooth feel.

With Analog Display—Watch the display update as the spindle moves for easy-to-read, trustworthy measurements.

Calibration Certificate—Choose these micrometers when precision measurements are required for quality control or by regulation. The certificate is traceable to NIST, so you can be confident your measurements are correct and consistent.

Ratchet-Stop Thimble—Best for consistent, repeatable measurements. The spindle stops extending the moment it reaches your part, so it won’t overtighten. Hear and feel a satisfying click that confirms you’ve applied the right amount of pressure.

Outside Micrometer Sets

Stock up your shop so you always have the measuring range you need. These micrometers come in a convenient case to store and organize them in one place.

To find your exact measurements, read the scales on the sleeve and thimble. These micrometers are free of electronic components that could break if dropped or short-circuit if wet. You don't have to replace any batteries, so they're always ready for the job.

Mitutoyo—The go-to for machinists and engineers. Every part is made within a Mitutoyo automated factory and tested in-house in Japan. The spindle glides as you turn the thimble with a weighty, silky-smooth feel.

Starrett—Precision machined and tested in the U.S. These Starrett micrometers come packaged in their iconic wood case, so you'll be able to spot them on the busiest of bench tops.

Calibration Certificate—Choose these micrometers when precision measurements are required for quality control or by regulation. The certificate is traceable to NIST, so you can be confident your measurements are correct and consistent.

Friction Thimble—Control how tightly the spindle closes on your part without the risk of damaging it. You can keep extending the spindle in small increments once it reaches your workpiece but not enough to overtighten. The thimble will start to resist turning to let you know you’ve applied the right amount of pressure.

Ratchet-Stop Thimble—Best for consistent, repeatable measurements. The spindle stops extending the moment it reaches your part, so it won’t overtighten. Hear and feel a satisfying click that confirms you’ve applied the right amount of pressure.
